Question

why is the stereocenter on the left R?

This image represents the structural formula of a complex organic compound. The diagram provides details of the specific stereoisomers and geometric isomers present in the molecule. 

### Explanation of the Diagram:
1. **Structural Representation**: The structure shows a variety of atoms interconnected by different types of bonds. Atoms include carbon (C), hydrogen (H), chlorine (Cl), bromine (Br), and a benzene ring (C6H5). 

2. **Stereochemistry**: 
    - The (R) and (S) notations indicate chiral centers within the molecule, where (R) represents the rectus (right) configuration and (S) the sinister (left) configuration.
    - (E) represents the trans configuration in alkenes, indicating that the highest priority substituents are on opposite sides of the double bond.

3. **Functional Groups and Bonds**:
    - The molecule includes a cyclohexane ring, indicated by six carbons forming a hexagonal ring.
    - There are different types of lines used to show the three-dimensional arrangement (bold for bonds coming out of the plane, dashed for bonds going behind the plane).

4. **Substituents and Functional Groups**: 
    - OR Cl: A chlorine atom attached to the cyclohexane ring.
    - OH C: A hydroxyl group attached to a carbon, indicative of an alcohol group.
    - Br: A bromine atom.
    - A benzene ring attached at one end, indicative of a phenyl group (aromatic ring).

5. **Complex Organic Molecule**: The arrangement of atoms and bonds signify a complex organic molecule, common in chemical synthesis and pharmaceutical chemistry.

### Educational Value:
Understanding such structures helps in learning the basics of organic chemistry, particularly stereochemistry which is crucial in fields like drug design, synthesis of complex organic molecules, and understanding biochemical interactions. This example emphasizes the importance of precise three-dimensional configurations in determining the properties and activities of molecules.
